Garton Maxwell "Gar" Hone (21 February 1901 – 28 May 1991) was an Australian medical practitioner noted as a tennis player of the 1920s and 1930s who also played first-class cricket for South Australia.

He excelled at various sports while growing up and earned Half Blues in tennis, Australian rules football and cricket at the University of Adelaide.

While at University, Hone played his only first-class cricket match, for South Australia against Victoria in the 1919/20 Shield season.

A right-handed top order batsman, Hone made two and eighteen, being dismissed leg before wicket by Warwick Armstrong.

In 1925 he had his best ever showing in the men's doubles, with a semi final appearance, after teaming up with Rupert Wertheim.
